In addition, compatibility may also indicate what the content played or reproduced in a first application may be reproduced or played by a second application.

The control unit 110 of the host apparatus 100 may determine the application compatibility by determining whether a product name of the first video player application 500 is included in media information of the accessory switch request message 632 received from the target apparatus 200. For example, if the media information of the accessory switch request message 632 includes the first video player application 500, the control unit 110 of the host apparatus 100 may determine the first video player application 500 as “compatible”. If the media information of the accessory switch request message 632 does not include the first video player application 500, the control unit 110 of the host apparatus 100 may determine the first video player application 500 as “incompatible”.

The control unit 110 of the host apparatus 100 may previously store, in the storage unit 180, host apparatus media information corresponding to the media information of the accessory switch request message 632 received from the target apparatus 200. The host apparatus media information may be a list of applications that have compatibility corresponding to content (e.g., a video, an audio, a web, etc.).

The control unit 110 of the host apparatus 100 may determine the application compatibility by determining whether the second video player application 501 is included in the host apparatus media information. The second video player application 501 is included in the media information of the accessory switch request message 632 received from the target apparatus 200. For example, if the second video player application 501 is included in the host apparatus media information, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “compatible”. If the second video player application 501 is not included in the host apparatus media information, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “incompatible”.

The control unit 110 of the host apparatus 100 may determine the application compatibility by determining whether the second application information received from the target apparatus 200 is included in the host apparatus media information. For example, if the host apparatus media information includes the second application information (e.g., an identifier, a product name, a classification code, etc. of the second application), the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “compatible”. If the host apparatus media information does not include the second application information, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “incompatible”.

The control unit 110 of the host apparatus 100 may determine the application compatibility by determining whether the second video player application 501 is same as the first video player application 500 executed in the host apparatus 100. The second video player application 501 is included in the media information of the accessory switch request message 632 received from the target apparatus 200. For example, if the first video player application 500 and the second video player application 501 are the same, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “compatible”. If the first video player application 500 and the second video player application 501 are different from each other, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “incompatible”.

In the analysis with respect to the compatibility between the first video player application 500 of the host apparatus 100 and the second video player application 501 of the target apparatus 200, the control unit 110 of the host apparatus 100 may determine whether the second video player application 501 of the target apparatus 200 has the compatibility, by using extensions (e.g., avi, mkv, wmv, mp4, etc.) of contents or by using codecs (e.g., mpeg, mpg, divx, xvid, h.264, etc.) supported by the first video player application 500. For example, content that is reproduced in the first video player application 500 of the host apparatus 100 may not be reproduced due to its video codec that is not supported by the compatible second video player application 501 of the target apparatus 200. In this regard, the control unit 110 of the host apparatus 100 may analyze the application compatibility, in consideration of the example case. For example, if at least one of codec of the first video player application 500 of the host apparatus 100 and extension of content is compatible with the second video player application 501 of the target apparatus 200, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “compatible”. If all of codec of the first video player application 500 of the host apparatus 100 and extension of content is not compatible with the second video player application 501 of the target apparatus 200, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “incompatible”.

When the host apparatus 100 analyzes the application compatibility between the first video player application 500 and the second video player application 501 of the target apparatus 200, the control unit 110 of the host apparatus 100 may determine whether the second video player application 501 of the target apparatus 200 has the compatibility, by using a screen size of the host apparatus 100, resolution of content and a screen size of the target apparatus 200, or resolution of content that is supported by the second video player application 501. For example, if the screen size of the host apparatus 100, the resolution of the content and the screen size of the target apparatus 200, or the resolution of the content that is supported by the second video player application 501 are compatible with each other, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “compatible”. If the screen size of the host apparatus 100, the resolution of the content and the screen size of the target apparatus 200, or the resolution of the content that is supported by the second video player application 501 are not compatible with each other, the control unit 110 of the host apparatus 100 may determine the second video player application 501 as “incompatible”.

When an application that is a compatibility comparison target object is not a video player application but is another application (e.g., an audio player application (not shown)), the control unit 110 of the host apparatus 100 may determine compatibility of the audio player application by using extensions (e.g., mp3, way, etc.) of content or codecs (e.g., ac3, dts, flac, wma, etc.) supported by the audio player application.

The control unit 110 of the host apparatus 100 may perform a compatibility comparison not only on the video player application and the audio player application, but also may perform a compatibility comparison on other applications.

The control unit 110 of the host apparatus 100 may store compatibility comparison information in the storage unit 180. The stored compatibility comparison information may include a compatibility comparison identifier for a history management, application information related to the compatibility comparison target object, a position of the media information, a comparison time, a compatibility comparison result (e.g., “compatible” and “incompatible”), or the like.

When the host apparatus 100 performs the compatibility comparison, the host apparatus 100 is connected in a wireless manner with each of the target apparatus 200 and the external apparatus 300. Here, the target apparatus 200 is not connected in a wireless manner with the external apparatus 300.

In operation S308 of FIG. 3, the host apparatus 100 determines to switch a wireless connection with the external apparatus 300 (operation S408). In addition, the host apparatus may determine whether to switch the wireless connection based on other parameters such as security information, license information, etc.

In correspondence to the compatibility comparison result (e.g., determined as “compatible”), the control unit 110 of the host apparatus 100 may determine to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200. The external apparatus 300 interoperates with the host apparatus 100. By using the stored compatibility comparison information (e.g., determined as “compatible”), the control unit 110 of the host apparatus 100 may determine to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200. The external apparatus 300 interoperates with the host apparatus 100. In correspondence to the compatibility comparison result (e.g., determined as “incompatible”), the control unit 110 of the host apparatus 100 may determine to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200. The external apparatus 300 then interoperates with the host apparatus 100.

When the control unit 110 of the host apparatus 100 determines “incompatibility” according to the compatibility comparison result, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, substitution information by which the target apparatus 200 can execute (or download) another video player application that substitutes for the second video player application 501.

The control unit 110 of the host apparatus 100 may store, in the storage unit 180, switch determination information with respect to the external apparatus 300. The stored switch determination information with respect to the external apparatus 300 may include a switch determination identifier for a history management with respect to the external apparatus 300, information about the external apparatus 300 that is a switch target, an identifier of the host apparatus 100, an identifier of the target apparatus 200, a switch determination time with respect to the external apparatus 300, the compatibility comparison result (e.g., determined as “compatible” or “incompatible”), or the like.

When the host apparatus 100 determines to switch the wireless connection with the external apparatus 300, the host apparatus 100 is connected in a wireless manner with each of the target apparatus 200 and the external apparatus 300. Here, the target apparatus 200 is not connected in a wireless manner with the external apparatus 300.

In operation S309 of FIG. 3, the host apparatus 100 requests the external apparatus 300 for a host apparatus change, and receives a response thereto from the external apparatus 300 (operation S409).

When the host apparatus 100 determines to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200, the control unit 110 of the host apparatus 100 may request the external apparatus 300 that is the switch target for the host apparatus change. For example, the host apparatus 100 may request the external apparatus 300 to change the host apparatus 100, which is a current host apparatus, to the target apparatus 200 that is another host apparatus. The control unit 110 of the host apparatus 100 may transmit not only a request for the host apparatus change but may also transmit apparatus information of the target apparatus 200 (hereinafter, referred to as “target apparatus information”) that is stored in the storage unit 180 to the external apparatus 300.

The target apparatus information stored in the host apparatus 100 may include wireless connection information (e.g., an SSID, an IP address, a MAC address, a channel number, a security key, etc.), a product name of the target apparatus 200, an identifier of the target apparatus 200, an MAC address of the target apparatus 200, a type of the target apparatus 200, a profile of the target apparatus 200, a communication method of the target apparatus 200, or the like. The control unit 110 of the host apparatus 100 may transmit not only the request for the host apparatus change but may also transmit a part (e.g., recognizable or settable the target apparatus 200 as a new host apparatus) of the target apparatus information stored in the storage unit 180 to the external apparatus 300.

The control unit 310 of the external apparatus 300 may receive the request for the host apparatus change via the communication unit 330. In correspondence to the request for the host apparatus change, the control unit 310 of the external apparatus 300 may set so that the preset host apparatus 100 can be changed to the new host apparatus that is the target apparatus 200. In response to the request for the host apparatus change, the control unit 310 of the external apparatus 300 may temporarily (or for a short period) store, in the storage unit 380, a change from the preset host apparatus 100 to the new host apparatus 200.

When the target apparatus 200 and the external apparatus 300 are connected in a wireless manner with each other (or via a wireless link set-up), the control unit 310 of the external apparatus 300 may set (or may change) the temporarily-stored new host apparatus as the target apparatus 200. When the target apparatus 200 and the external apparatus 300 attempt to perform wireless connection (or the wireless link set-up), the external apparatus 300 may first search for the target apparatus 200 by using the stored target apparatus information.

The control unit 310 of the external apparatus 300 may transmit a response to the request for the host apparatus change via the communication unit 330. The control unit 310 of the external apparatus 300 may transmit, via the communication unit 330, a response about one of “the host apparatus change is accepted” and “the host apparatus change is not accepted” to the host apparatus 100. The control unit 310 of the external apparatus 300 may transmit, via the communication unit 330, a response about one of “the host apparatus change is completed”, “the host apparatus change is to be performed”, and “the host apparatus change has an error” to the host apparatus 100.

The control unit 110 of the host apparatus 100 may receive, from the external apparatus 300, the response to the request for the host apparatus change (e.g., “the host apparatus change is accepted”, etc.) by using the communication unit 130. The control unit 110 of the host apparatus 100 may store the received response to the request for the host apparatus change in the storage unit 180.

When the host apparatus 100 requests the external apparatus 300 for the host apparatus change, and receives the response thereto from the external apparatus 300, the host apparatus 100 is connected in a wireless manner with each of the target apparatus 200 and the external apparatus 300. Here, the target apparatus 200 is not connected in a wireless manner with the external apparatus 300.

In operation S310 of FIG. 3, a response to an external apparatus switch request is transmitted from the host apparatus 100 to the target apparatus 200 (operation S410).

In correspondence to the compatibility analysis and the response, which is received from the external apparatus 300, to the request for the host apparatus change, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, the response to the external apparatus switch request (e.g., the accessory switch request response message 632 b). When the compatibility analysis result by the host apparatus 100 indicates “compatible” and the host apparatus 100 receives the response to the request for the host apparatus change from the external apparatus 300, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, the response to the external apparatus switch request received from the target apparatus 200.

When the compatibility analysis result by the host apparatus 100 indicates “incompatible” or the host apparatus 100 does not receive the response to the request for the host apparatus change from the external apparatus 300, the control unit 110 of the host apparatus 100 may not transmit, to the target apparatus 200, the response to the external apparatus switch request received from the target apparatus 200.

The accessory switch request response message 632 b may have a format shown in Table 2.

TABLE 2 Syntax Size(bit) Notes Accessory_Response_Format( ) { — Management message type=n 4 Host_Device_ID 6 Accessory_mapping_ID 8 0000: Microphone 0001: Headphone 0010: Music instrument 0011: Speaker 0100: Headset • • • Target_Device_ID 6 Access_authority_info 2 00: Yes 11: No Web_source_info 2 00: Yes 11: No Reserved 1 } —

An external apparatus mapping identifier field (i.e., accessory_mapping_ID) may indicate an identifier of the external apparatus 300 that interoperates with the host apparatus 100. For example, a microphone field may be “0000”, a headphone field may be “0001”, a music instrument field may be “0010”, a speaker field may be “0011”, or a headset field may be “0100”. In addition, the number of the external apparatus mapping identifiers may be added, deleted, or changed in one or more exemplary embodiments.

A target apparatus identifier field (i.e., target_device_ID) may indicate an identifier of the target apparatus 200 that requested the host apparatus 100 to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200. An access authority information field (i.e., Access_authority_info) may indicate an access authority (e.g., access allowed or access denied) of the target apparatus 200 with respect to the external apparatus 300. The access authority information field may indicate all of the access authority (e.g., access allowed or access denied) of the target apparatus 200 with respect to the external apparatus 300 and an access authority (e.g., access allowed or access denied) of the host apparatus 100 with respect to content.

A web source information field (i.e., Web_source_info) may indicate whether a web server address (or a separate storage device location) is required. For example, when compatibility between the second video player application 501 of the target apparatus 200 and the first video player application 500 is determined, the control unit 110 of the host apparatus 100 may define the web source information field as “00” so as to correspond to a web server address (or a separate storage device location) where the first video player application 500 or another video player application (not shown) that is compatible with the first video player application 500 is stored. If the web source information field is set as “00”, the control unit 110 of the host apparatus 100 may add the web server address (the separate storage device location or substitution information, e.g., www.samsung.com/server1) to an additional field (not shown) of the accessory switch request response message 632 b.

The accessory switch request response message 632 b may be stored in the storage unit 275, according to control by the control unit 110 of the host apparatus 100. The control unit 110 of the host apparatus 100 may receive the accessory switch request response message 632 b from an external source (a separate server (not shown)) and may store the accessory switch request response message 632 b in the storage unit 275.

In another exemplary embodiment, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, the response to the external apparatus switch request (e.g., the accessory switch request response message 632 b and the compatible application message 632 c). When the compatibility analysis result indicates “incompatible” and the host apparatus 100 receives the response to the request for the host apparatus change from the external apparatus 300, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, the response to the external apparatus switch request received from the target apparatus 200 and the compatible application message 632 c.

When the compatibility analysis result indicates “compatible” and the host apparatus 100 receives the response to the request for the host apparatus change from the external apparatus 300, the control unit 110 of the host apparatus 100 may transmit, to the target apparatus 200, the response to the external apparatus switch request received from the target apparatus 200, and may not transmit the compatible application message 632 c to the target apparatus 200.

In correspondence to the compatibility analysis result (e.g., “compatible” or “incompatible”), the control unit 110 of the host apparatus 100 may transmit another accessory switch request response message to the target apparatus 200. For example, a field for the accessory switch request response message 632 b may vary according to the compatibility analysis result.

The compatible application message 632 c may have a format shown in Table 3.

TABLE 3 Syntax Size(bit) Notes Accessory_Response_Format( ) { — Management message type=n 4 Compatible_info 8 0000: media player1 0001: video player1 0010: video player2 0011: video player3 0100: video player4 • • • Compatible_format 8 0000: avi 0001: mkv 0010: mp4 0011: asf 0100: wma • • • Web_source_info 2 00: Yes 11: No Host_Device_ID 6 Target_Device_ID 6 Accessory_mapping_ID 6 } —

Here, a management message type field (i.e., Management message type) may indicate “3” corresponding to a type of the compatible application message 632 c (e.g., compatible_res). A compatible information field (i.e., Compatible_info) may indicate an application capable of executing content that is executed in the host apparatus 100. The application capable of executing the content that is executed in the host apparatus 100 may include an application installed in the target apparatus 200 and an application (e.g., a video player3 and a video player4) uninstalled in the target apparatus 200. A compatible formation field (i.e., Compatible_format) may indicate a format of compatible content. A web source information field (i.e., Web_source_info) may indicate whether a web server address (or a separate storage device location) is required.

A host device identifier field (i.e., host_device_ID) may indicate an identifier of the host apparatus 100 that is initially interoperates with the external apparatus 300 and receives the external apparatus switch request from the target apparatus 200.

A target apparatus identifier field (i.e., target_device_ID) may indicate an identifier of the target apparatus 200 that requested the host apparatus 100 to switch the wireless connection with the external apparatus 300 from the host apparatus 100 to the target apparatus 200. An external apparatus mapping identifier field (i.e., appessory_mapping_ID) may indicate an identifier of the external apparatus 300 that interoperates with the host apparatus 100.

The compatible application message 632 c may be stored in the storage unit 275, according to control by the control unit 110 of the host apparatus 100. The control unit 110 of the host apparatus 100 may receive the compatible application message 632 c from an external source (a separate server (not shown)) and may store the compatible application message 632 c in the storage unit 275.

When the host apparatus 100 transmits the response to the external apparatus switch request to the external apparatus 300, the host apparatus 100 is connected in a wireless manner with each of the target apparatus 200 and the external apparatus 300. The target apparatus 200 is not connected in a wireless manner with the external apparatus 300.

In operation S311 of FIG. 3, the target apparatus 200 determines an access authority (operation S411).

The control unit 210 of the target apparatus 200 may receive, from the host apparatus 100, the response to the external apparatus switch request (e.g., the accessory switch request response message 632 b) by using the mobile communication unit 220 and/or the sub-communication unit 230.

The control unit 210 of the target apparatus 200 may determine the second video player application 501 as compatible, in correspondence to reception of the accessory switch request response message 632 b. The compatible second video player application 501 may execute, by control of the control unit 210, content that is reproduced in the first video player application 500. The control unit 210 of the target apparatus 200 may determine whether to reproduce, via the second video player application 501, the content that is reproduced in the first video player application 500, by using the compatible information field of the compatible application message 632 c.

The control unit 210 of the target apparatus 200 may determine an access authority with respect to the external apparatus 300, by using the access authority information field of the accessory switch request response message 632 b.

The control unit 210 of the target apparatus 200 may store the accessory switch request response message 632 b in the storage unit 275. The control unit 210 of the target apparatus 200 may receive the accessory switch request response message 632 b from an external source (e.g., a separate server (not shown) and may store the accessory switch request response message 632 b in the storage unit 275.

The control unit 210 of the target apparatus 200 may receive the response to the external apparatus switch request (e.g., the accessory switch request response message 632 b and the compatible application message 632 c) by using the mobile communication unit 220 and/or the sub-communication unit 230. The control unit 210 of the target apparatus 200 may determine an access authority with respect to the external apparatus 300 and a content access authority with respect to the host apparatus 100, by using the access authority information field of the accessory switch request response message 632 b.

The control unit 210 of the target apparatus 200 may store the accessory switch request response message 632 b and the compatible application message 632 c in the storage unit 275. The control unit 210 of the target apparatus 200 may receive the accessory switch request response message 632 b and the compatible application message 632 c from an external source (e.g., a separate server (not shown) and may store the accessory switch request response message 632 b and the compatible application message 632 c in the storage unit 275.

When the target apparatus 200 determines the access authority, the host apparatus 100 is connected in a wireless manner with each of the target apparatus 200 and the external apparatus 300. The target apparatus 200 is not connected in a wireless manner with the external apparatus 300.

In operation S312 of FIG. 3, the target apparatus 200 and the external apparatus 300 are connected with each other (operation S412).

Referring to FIG. 5D, the control unit 210 of the target apparatus 200 may search for the external apparatus 300 by using the accessory switch request response message 632 b received via the mobile communication unit 220 and/or the sub-communication unit 230. The control unit 210 of the target apparatus 200 may search for the adjacent external apparatus 300 by using an external apparatus mapping identifier. The control unit 210 of the target apparatus 200 may search for the external apparatus 300 by using pre-stored external apparatus information. The control unit 210 of the target apparatus 200 may be connected to the external apparatus 300 by using the external apparatus mapping identifier and the external apparatus information. The external apparatus 300 that is a connection target may be selected, by a user, from a search list (not shown) corresponding to a search result displayed on a screen of the target apparatus 200, and may be connected with the target apparatus 200.

When the target apparatus 200 and the external apparatus 300 are connected with each other, the control unit 210 of the target apparatus 200 may transmit a notice about completion of the connection between the target apparatus 200 and the external apparatus 300 to the host apparatus 100.

In operation S312 of FIG. 3, the connection between the target apparatus 200 and the external apparatus 300 is substantially similar (e.g., the target apparatus 200 is a changed host apparatus, and the connection is performed by using the stored external apparatus information) to the connection between the host apparatus 100 and the external apparatus 300 in operation S301 of FIG. 3, thus, redundant descriptions thereof are omitted here.

When the target apparatus 200 and the external apparatus 300 are connected, the host apparatus 100 is connected in a wireless manner with the target apparatus 200. The target apparatus 200 is connected in a wireless manner with each of the host apparatus 100 and the external apparatus 300.

In operation S313 of FIG. 3, content is transmitted from the host apparatus 100 to the target apparatus 200 (operation S413).

The control unit 110 of the host apparatus 100 may transmit the content, which is reproduced in the first video player application 500, to the target apparatus 200 via the communication unit 130.

After the host apparatus 100 is connected with the target apparatus 200 or after the target apparatus 200 and the external apparatus 300 are connected, the control unit 110 of the host apparatus 100 may transmit the content to the target apparatus 200. When the host apparatus 100 is connected with the target apparatus 200, the control unit 110 of the host apparatus 100 may transmit at any time the content to the target apparatus 200. When the host apparatus 100 is connected with the target apparatus 200, the control unit 110 of the host apparatus 100 may transmit at any time the content to the target apparatus 200, in response to a content transmission request (not shown) from the target apparatus 200.

The control unit 110 of the host apparatus 100 may transmit not only the content but also first application information (e.g., a first video player application) stored in the storage unit 180 to the target apparatus 200. The control unit 110 of the host apparatus 100 may transmit not only the content but also a part of the first application information (e.g., a first video player application) stored in the storage unit 180 to the target apparatus 200. The transmitted part of the first application information may include application execution state information (e.g., a reproduction position of content, a current level of content (e.g., a game), etc.) that corresponds to a transmission time of the first application information.

When the content is transmitted from the host apparatus 100 to the target apparatus 200, the host apparatus 100 and the target apparatus 200 are connected in a wireless manner with each other. The target apparatus 200 is connected in a wireless manner with each of the host apparatus 100 and the external apparatus 300.

In operation S314 of FIG. 3, the content is output from the target apparatus 200 to the external apparatus 300 (operation S414).

Referring to FIG. 5D, when the content is received from the host apparatus 100, the control unit 210 of the target apparatus 200 may reproduce the content in the second video player application 501. The control unit 210 of the target apparatus 200 may seamlessly reproduce the content in the second video player application 501 by using the first application information. The control unit 210 of the target apparatus 200 may store the content and the first application information in the storage unit 275.

The control unit 210 of the target apparatus 200 may provide a user with a feedback corresponding to the content execution (e.g., an output of the content from the target apparatus 200 to the external apparatus 300) in the second video player application 501. The feedback provided by the target apparatus 200 is one of a visual feedback, an acoustic feedback, and a tactile feedback. The control unit 210 of the target apparatus 200 may provide the user with one of the visual feedback, the acoustic feedback, and the tactile feedback or a combination of the visual feedback, the acoustic feedback, and the tactile feedback.

The visual feedback may be displayed as a visual effect (e.g., a separate image or an animation effect such as a fade applied to the separate image) corresponding to the content execution (e.g., the output of the content from the target apparatus 200 to the external apparatus 300) in the second video player application 501. The visual effect differs from the content displayed in the second video player application 501. The acoustic feedback may be output, via the speaker 263, as a sound corresponding to the content execution (e.g., the output of the content from the target apparatus 200 to the external apparatus 300) in the second video player application 501. The tactile feedback may be output, via the vibration motor 264, as a vibration corresponding to the content execution (e.g., the output of the content from the target apparatus 200 to the external apparatus 300) in the second video player application 501.

In a configuration setting (not shown) of the target apparatus 200, the user may select and/or may change the feedback (e.g., at least one of the visual feedback, the acoustic feedback, and the tactile feedback) corresponding to the content execution (e.g., the output of the content from the target apparatus 200 to the external apparatus 300) in the second video player application 501.

The user may input and/or may change a feedback provision time (e.g., 700 msec, changeable) during which at least one feedback is provided to the user.

The control unit 210 of the target apparatus 200 may output, to the external apparatus 300, the content that is reproduced in the second video player application 501. The control unit 310 of the external apparatus 300 may output the content via at least one of the display unit 370 and the speaker 375. For example, when the content is video, the control unit 310 of the external apparatus 300 may output the content via the display unit 370 and the speaker 375. When the content is audio, the control unit 310 of the external apparatus 300 may output the content via the speaker 375.

The control unit 310 of the external apparatus 300 may provide the user with a feedback corresponding to the output of the content.
